Cheese Making

Kit #5

In this multi-day, multi-part activity, students turn milk into cheese. Throughout the process they observe, describe, and compare the various materials produced. They first culture the milk with non-toxic bacteria, which begins the curdling process. Once the bacteria have had sufficient time to act on the milk, an enzyme is added to hasten clotting and the separation of the curds and whey. Finally, they strain the mixture to remove the whey then compress and refrigerate the curd to cure it into cheese.
